Running an online store on Cafe24, you end up moving the same data to several places. Copying new orders into the settlement sheet, removing sold-out products from the inventory sheet, alerting someone when a large order comes in. Cafe24 provides an official API for exactly this kind of connection. We've built Cafe24 API integrations ourselves, and here's the order of decisions we found worth settling from the start.
1. Start with what data goes where
Before choosing an API (the channel programs use to exchange data), it helps to write down what data you'll move and where it will go. Cafe24's official guide describes two kinds of API.
| Type | Official description | Use it when |
|---|---|---|
| Admin API | For store administrators — managing products, orders, members, and categories | Orders into a settlement sheet, product info into an inventory sheet |
| Front API | For the storefront — product lookup, cart, order/checkout | Showing products on another screen |
Most business automation starts with the Admin API. Write one line each for "when an order comes in, what moves, where, and how often," and deciding permissions and call frequency later becomes much easier.
2. App registration and the OAuth flow
To use the Cafe24 API, you first register an app in the Cafe24 Developer Center and receive credentials. Then the store operator grants access through OAuth 2.0 (a way to lend an app permissions without handing over your password). The official guide's flow looks like this.
- Request an authorization code: This is requested from the web browser. The code you receive is valid for 1 minute and can be used only once.
- Issue an Access Token: Exchange the code for the token used in actual API calls. This request must be made from the server (backend).
- Token lifetimes: The Access Token lasts 2 hours, and the Refresh Token (the key for getting a new token) lasts 2 weeks.
Register the address the user returns to after authentication (the Redirect URI) in the Developer Center ahead of time, and send the same address when requesting tokens. The official guide says to always use HTTPS.
3. Request only the permissions you need
During authentication you also set the permission scope — which data the app can access. The official examples include names like mall.read_order (read orders) and mall.read_product (read products).
If you're only reading orders to move them into a settlement sheet, read permissions are all you need. With write permissions, a single mistake can change live store data. We recommend starting with read access and adding permissions only when a feature truly needs them, such as editing products.

Cafe24's getting-started guide lists call limits of 10 per second and 300 per minute, and says exceeding them returns a 429 Too Many Requests response. On busy order days, trying to move a lot of data at once makes it easy to hit this limit.
- Queue requests and send them in turn within the limit
- When you get a 429, wait briefly and try again
- Since the Access Token expires after 2 hours, refresh it before it expires
- If a refresh fails, alert the person in charge right away
Building these four into the initial design greatly reduces "the integration that worked fine yesterday suddenly stopped."
AI features you can add after integration (optional)
Once data is flowing reliably, adding AI features is worth considering. For example, generating draft product descriptions from product data for staff to polish, or classifying customer inquiries into shipping, exchange, and product questions and routing them to the right person. The right order is to add these as options after the integration is stable.
Pre-integration checklist
- Did you write down, line by line, the data to move and the receiving system?
- Developer Center app registration · Redirect URI registration
- Permissions (scope) kept minimal, starting with read
- Did you build call limits, token refresh, and failure alerts into the design?
